Answer:
Throw this sample out and start over again with a better sampling method
Step-by-step explanation:
Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.
Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.
Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
13x^2+6x+12-7/17x+4
this is the answer i got
4v/27 = 16
You have to get rid of the 27 in the denominator, do so by multiplying both sides by the 27.
Now you have:
4v = 432
Next you need to get rid of the 4 by dividing both sides by 4
Your answer is now:
v = 108
B is the correct answer because categorial means choosing which are the most likely to get chosen.
